why the up vote? no research of your own, clearly just fishing for information to a school assignment. I'm sorry, but if you don't have a clue, you don't want to write a shell and no matter what this is not the place to ask information about it.

Notice that this does not survive grub2-mkconfig, and also notice that this is not the recommended method, but since you did link to the recommended and didn't get that to work, I feel it's ok to suggest this, because this does work.

After that you might want to remove or disable the repo. Look for /etc/yum.repos.d for the new fedorautils.repo, edit (ENABLED=0) or remove the file alltogether. If it replaced some packages when it was installed, they should be downgradable afterwards with yum downgrade.

How to live with it and modify it, well that's a discussion that should take place within the external project itself.

Any chance the laptop has a wireless toggle which happens to be off? Most laptops these days have such a key or a key combination. Sometimes a dedicated switch and sometimes a Fn + some F1-F12 button with an antenna logo with some waves around. Based on images.google.com a pavillion g6 has that feature in Fn+F12.

Disabled how? Where does it show that it's disabled? Does it work in Windows? Did you read your post (the unformatted lspci is not exactly fun to read)? If you want answers it's best to show a little effort yourself, too.

Wonky kernel versions you got there. Fedora 18 has 3.6.something in its installer and now upgraded runs 3.7.4. What graphics card are you using? And if it's nvidia or ati, did you have some extra drivers installed for it, back when it was 17 (I assume, you only mentioned "to 18 from 18"). In any case, boot up with the alternative "3.03" and run a yum upgrade from there and see where that gets you in terms of bootability.

You sure it's not somewhere closer to layouts? KDE has it there, many alternatives for layout switching that cannot be used for shortcuts to other stuff quite as easily. And if gnome3 is getting on your nerves, try something different, e.g. kde or xfce.

You might want to be a little more verbose about where and how it gets stuck during resume. Or don't you see anything as it starts to wake up? Which window manager you're using is also an important factor here.

It'd help to know which version of Fedora you're trying to install, and which install media you're trying with. Servers can be trickier than desktops with their user interfaces. But at that point, if I understood you correctly, you're still in syslinux/isolinux, doesn't the timer roll? or isn't the keyboard active? (frankly, I'd go with RedHat / CentOs in the firstplace anyway, unless you have some solid reasons to go with a beelding-edge distribution like Fedora)

Almost everything is there, but perhaps most notably hw graphics acceleration (especially 3D) will not be available. Other than that, I can't think of other notable features that wouldn't be there. Gfx is just understandably sluggish.
